@dc42 Can you choose whether to use UART through which gcode codes of RRF?

@dc42 The specification is the same as that of 4988, which is equivalent to an ordinary 4988 driver. UART cannot be used

@dc42 @dc42 It seems that the external closed-loop driver connected to me does not use UART interface. It should not be affected by reason, unless reprofirmware is set and affected in this way. This may be a step timing problem. M569 P5 R1 T2. 5:2.5:5:0 ; Driver 5 requires high level active enable, 2.5us minimum step pulse, 2.5us minimum step interval, 5us dir setup time and no hold time. How large should I set? The line length is 1m. Is the default timing size of duet3 0.

@dc42 I need to use two closed-loop interfaces, but the closed-loop driver I use is used as an ordinary 4988 driver on duet3 motherboard. Can I ask whether these two interfaces can be used directly. My driver needs the six pins of "EN STP DIR COM VIN GND", which is equivalent to using the closed-loop as an ordinary driver

@mejituu About duet3mini5plus how to turn off UART mode to use third-party closed loop.I have a duet3mini5plus. By blowing down the 2209 chip and leading out the corresponding drive pins, I can make the external third-party closed-loop move through these pins. However, due to the offset problem in the printing process due to UART mode, how can I set the motor drive to turn off UART to use the closed-loop. Excuse me, this M569 P0.0 S1 D4 can turn off UART mode directly, and whether M569 .1needs to be configured. How to configure M569.1 if necessary one.
